Water/Methanol/Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone.
The key to a safe and effective WMI setup is tuning integration. All BMS kits integrate into the JB4 tuning system allowing for precise mapping based on boost, throttle position, engine speed, intake temperature, advance, gear, and other data elements available to the JB4 through its CANbus system. In addition, a pump flow signal is fed back to the JB4 allowing for a safe and smooth progressive boost mapping. If the tank runs empty or flows drops for any reason the JB4 will safely back down performance to avoid knock. In addition, WMI can be activated or disabled from the driver’s seat, will automatically disengage during traction control or safety map situations, and WMI flow data can be displayed in-dash and/or via your JB4 Mobile logging device.
